RAILWAY-CARRIAGE AND LIKE WINDOW.

Specification of Letters Patent. Patented 11/13 1 4 1922;

Application filed March 26, 1914, Serial No. 827,516. Renewed January 6, 1917. 4 Serial No. 140,960%.

T 0 all whom it may concern:

Be it known that 1, MAX RITTER, a subject of the Emperor of Germany, residlng at Dresden, Germany, have invented certain Improvements in RailwayC arriage and like lVindows, of which the following 1s a specification.

The present invention relates to a'sliding window such as employed in railway carriages and the like and actuated by springs which balance the window. The invention consists in the pro-vision of a pivoted springactuated weather strip having a cork or like fillet which is normally applied to the window pane under the influence of the strip springs. Arms on the weather strip cooperate with lugs fitted on an eccentric shaft which is employed for securing the sliding sash in the desired position, the arrang' ment being such that the strip is withdrawn from the pane by the lugs when the shaft is turned for releasing the window sash and allowed to close when the shaft is turned for securing the sash.

In the accompanying drawings the invention is illustrated,

Fig. 1 representing a front view of the window, part of the casing being removed to show the interior,

Fig. 2, a vertical section on the line A--B of Fig. 1,

Fig. 3, a sectional view on a larger scale of the weather strip and the operating shaft, and

Fig. i, a partial plan of the strip and the shaft.

The sliding window 6 is fitted in the usual manner in stiles .1 and is secured inthe desired position by an eccentric shaft 0 operacted by means of a handle p. The window is spring-balanced for which purpose it is supported on rollers e carried at the free ends of two arms 0 and (Z which are pivoted to brackets 7'. Spiral springs 71, held in the brackets 7", are fitted at their free ends 2' with rollers 7a which bear against the arms (Z thereby tending to raise the window. The spindles g on which the springs h are mounted, are also fitted with a pawl-andratchet mechanism, and they project through the window casing so that they can be turned from the outside for adjusting the tension of the springs. The shaft 0 is journalled in bearings 0 secured-to the stiles 1', and it holds the window I) in position by pressing it against the projecting edges of the stiles. Knobs s are connected to the window. as a means for varying its position.

Pivo-ted at wl to the window sill a is a weather strip 10 which is actuated by. springs 3 so as to normally apply a cork or like fillet e to the window pane for leading off the rain water. Arms 1), connected to the strip to,

with lugs a2 connected'to the shaft 0. The,

arrangement is such that when the shaft 0" is turned into the position shown dotted in Fig. 3 for releasing the WElIlClOW b, the arms o are engaged by the lugs 00. for turning the strip to and retracting the fillet e from the window pane. When the shaft is turned. for securing the window in position, the arms '0 are released so as to allow the fillet to be applied to the. pane under the influence of the springs 3 The shanks ofthe handle are so arranged as to co-operate window. pane, and connections between said shaft and said weather strip for retracting the fillet from the pane when the shaft is turned for releasingithe window.

2. In railway carriage and like windows,

the combination withaspring-balanced slid-.

ing window. of an eccentric shaft for securing the window in adjusted position, a spring-actuated weather strip pivoted to the window sill, a cork fillet connected to said strip so as to bear normally against the win-i dow pane, lugs connected to saidfs-haft, and

arms connected to the Weatherstrip so as to cooperate with said lugs, for retracting the fillet from the. pane when the shaft is turned for'releasing the window. 7 MAX BITTER. \Vitnesses:
